部分剪力连接钢──混凝土组合梁受弯极限承载力的计算

钢─混凝土组合梁在受弯承载力和变形许可的条件下采用部分剪力连接对于方便施工和降低造价等都是有利的。部分剪力连接对组合梁的受弯极限承载力和变形均有影响。本文通过对4根部分剪刀连接组合梁的试验研究和对国内外8根部分剪力连接组合梁受弯极限承载力的分析，建立了考虑剪力连接程度影响的组合梁受弯极限承载力计算公式。结果表明，按照本文公式得到的计算值与实测值吻合良好。

ULTIMITE FLEXURAL CAPACITY OF COMPOSITE STEEL-CONCRETE BEAMS WITH PARTIAL SHEAR CONNECTION

If the condition of flexural capacity and deflection is satisfied, partial shear connection can be used for the design of composite steel-concrete beams, which is beneficial to cost reduction and construction convenience. Shear connection degree has an effect on the flexural capacity and deflection of composite beams. Four specimens are investigated of composite beams with partial shear connection. According to the experimental research on the test beams and analyses of other available test results of 8 composite steel-concrete beams with partial shear connection, the formulae, with clear physical idea and mode, are derived for the ultimate flexural capacity with consideration of shear connection degree. The predicted values are in good agreement with experimental results.
